3(6x - 4) = 22x

pentagon [3]

First expand the brackets 18x-12=22x and then you move the 18x to the other side so 12=22x-18x 12=4x. 3=x

Please help, I'm stuck on this question

vesna_86 [32]

Answer: Option C

$a> 0$

Step-by-step explanation:

The graph shows a radical function of the form $f(x)=a(x+k)^{\frac{1}{n}}+c$

Where n is a positive number.

For this type of function, if the coefficient $a> 0$ then then when x tends to $\infty$ f(x) tends to $\infty$ and when x tends to $-\infty$ then f(x) tends to $-\infty$ .

Notice in the graph that as x increases then f(x) also increases and as x decreases f(x) also decreases.

This indicates that the coefficient $a> 0$

If the supplement of an angle is two-third of itself ,then its supplement is

stich3 [128]

( 'x' is not 144 .)

The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .

180 - x = 2/3 x

Multiply each side by 3 :
( Note: 3 x 180 = 540 .)

540 - 3x = 2x

Add 3x to each side:

540 = 5x

Divide each side by 5 :

<u>x = 108°</u> .
